Description
The Galtronics 04119261-05777-1 EXTENT D5777i is a professional-grade Low PIM Dual-Polarized MIMO Directional Panel Antenna designed for high-capacity cellular coverage, distributed antenna systems (DAS), and wireless telecommunications infrastructure. Operating across 698–960 MHz and 1710–2700 MHz frequency bands, this antenna delivers up to 15 dBi gain with approximately 30-degree horizontal and vertical beamwidth, providing focused directional RF coverage for demanding indoor and outdoor wireless installations.
The EXTENT D5777i features dual ±45° polarization with two independent RF ports, supporting MIMO wireless communication systems and high-capacity venue applications. Designed for locations such as stadiums, arenas, campuses, and commercial facilities, the antenna provides passive intermodulation performance better than -150 dBc, 50 Ohm impedance, and maximum input power handling of 250W per port. Its UV-resistant outdoor design features a white radome, IP65 environmental protection, and support for adjustable wall or pole mounting configurations using compatible mounting hardware.
